Format lost on dependency:tree command with outputFile parameter

[stauvel]

Hi !

I'm facing a strange behaviour with this code :

require('maven')
    .create({cwd: '/path/to/my/maven-project'})
    .execute(['dependency:tree'], { 'sort': true, outputFile: __dirname + '/dependencies.tree' });

The output format of tree (with +, - and \) is lost when I'm using an absolute path like ${__dirname}. For example :

 +- javax.mail:mail:jar:1.4:compile
|  \- javax.activation:activation:jar:1.1:compile

Will become :

javax.mail:mail:jar:1.4:compile
javax.activation:activation:jar:1.1:compile

• I'm under Windows 10 (sorry, not my choice)
• Using a relative path (.execute(['dependency:tree'], { 'sort': true, outputFile: 'dependencies.tree' });) is OK but generate the file in my Maven project folder (first workaround)
• Exexuting directly Maven command on a terminal under my Maven project folder and outputing the result file to my JS script folder (mvn dependency:tree -DoutputFile="/path/to/my/js-script/dependencies.tree") is OK, but breaks the automation (second workaround)

Finally, I can do my job with theses workarounds and thank you for this usefull library for scripting my Maven migration. But I spent a lot of my poor brain on this strange behaviour and maybe you could explain me the difference between terminal command and nodeJs script?
